Equus, sp. a. 



The following specimens probably belong either to E. major, De 

 Kay l , or E. occidentalis, Leidy 2 . Both these species have large upper 

 teeth, with the crowns slightly curved, and long anterior " pillars " ; 

 the latter species being distinguished by the smaller degree of the 

 plications of the enamel-folds 3 . Leidy states 4 that it is frequently 

 almost or quite impossible to specifically determine isolated teeth.
